China Telecom Tests Huawei's Transport SDN Controller

China Telecom Fujian (Fujian Telecom) and China Telecom Beijing Research Institute have tested Huawei's Transport SDN controller for implementing an intelligent private line Bandwidth on Demand (BoD) app for VIP customers.

The idea is to let VIP customers apply for private line services online, which would then be provisioned immediately over the optical transport network. In addition, tenants can adjust the service bandwidth of private lines in real-time based on traffic volume, making full use of bandwidth resources.   '

Zha Jun, President of Huawei Fixed Network Product Line, said, "Huawei cooperated with China Telecom to deploy the innovative BoD private line app based on the transport SDN. The deployment is a key milestone that effectively pushes progress of the transport SDN industry. Huawei will continue to cooperate with China Telecom in developing cutting-edge 400G, 1T, 2T, and SDN technologies, and building a flexible, synergetic, intelligent, and open next-generation transport network."

China Telecom Tests Huawei's Virtual Customer Premises Equipment

China Telecom Corporation Limited Beijing Research Institute completed live network tests of Huawei's Network Functions Virtualization (NFV) based Virtual Customer Premises Equipment (vCPE).

The idea with vCPE is to "cloudify" and simplify enterprise service functions, such as firewalls, that have traditionally been implemented in the CPE.  Upgrading such equipment is costly and slow, whereas changes can be more flexibly implemented in the network.

Mr. Chen Yunqing, Vice President, China Telecom Corporation Limited Beijing Research Institute, said, "Through this live network test of vCPE, we have realized the immense benefits of Network Functions Virtualization to carriers. This provides software and hardware support for future development and deployment of integrated Cloud services, helping carriers address challenges from cloud computing and big data."

The successful vCPE test demonstrates the partnership China Telecom and Huawei have developed. The two parties are also exploring the commercialization of NFV and Software-Defined Networking (SDN) on carrier networks. As industry leaders, Huawei and China Telecom will continue to develop new technologies and improve current network functions and architecture. Both parties aim to play a leading role in the commercialization and full popularization of NFV and SDN.

China Telecom Tests Embedded OTDR with Huawei

China Telecom has conducted the first commercial tests of Embedded OTDR (eOTDR) technology in its live fiber access network in Xinjiang province.

An optical time domain reflectometer (OTDR), uses scattered and reflected light to measure transmission quality along optical fibers, and is primarily used for fiber testing and troubleshooting. Huawei's eOTDR(Embedded OTDR)is embedded in an OLT PON optical module.  It works with the company's Line Assurance System iManager N2510 to effectively identify physical connections and optical fiber attenuation.

Huawei said its OTDR-embedded optical modules are the same size as standard optical modules and can be easily deployed on an FTTx network to assist with troubleshooting. This technique does not require serious network reconstruction, such as fiber connection modifications or optical network terminal (ONT) adjustment, nor does it interrupt services during the troubleshooting process.

China Telecom implemented Huawei's iManager N2510/eOTDR solution and completed testing across their entire live network. The test results demonstrated that this solution can locate all backbone fiber faults and the majority of branch fiber faults, work with a fiber Bragg grating (FBG) to demarcate faults and effectively reduce 40% O&M field engineer workload. Moreover, once ODN construction is completed, this solution can test fiber quality and maintain quality data, report alarms in the event of quality deterioration by implementing periodic testing and facilitate rapid response troubleshooting to reduce compliant and improve customer satisfaction. China Telecom has endorsed the test results.

China Telecom Carries Terabit Wavelength over 3,200km with ZTE

China Telecom Corporation Ltd. Beijing Research Institute carried a terabit wavelength over a distance of 3,200 kilometers on G.652 optical fiber without Raman amplification that was error-free for 24 hours.  The world record demonstration used ZTE’s ZXONE 8700 WDM platform and advanced Nyquist WDM Terabit PM-QPSK optical modulation and optical coherent detection technologies.  The system leveraged ultra-high-speed signal processing and soft-decision forward error correction algorithms, achieving spectral efficiency of 4bit/Hz/s.

ZTE said this latest demonstration strengthens its global leadership in terabit optical transport systems. In 2012, ZTE and Deutsche Telekom successfully completed 100G/400G/1T long-haul transmission over 2,450 kilometers, setting a record in long-distance multi-rate mixed transmission. ZTE has successfully deployed more than 50 100G trial and commercial networks globally.

ZTE noted that it achieved record revenue in optical network products in the second-quarter of 2013, achieving the industry’s fastest growth rate in the preceding 12-month period, according to data from research company Ovum.
